DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 635,360, dated October24, 1899.

Application filed July 17, 1899. Serial No. 724,140. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL H. TINSMAN, a citizen of the United States,residing at Rock Island, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements inDraft-Equalizers, of which the following is a specification, referencebeing had to the drawing accompanying and forming a part of thespecification, in

which the figure is a plan showing the draftequalizer attached to a plowbeam.

This invention relates to certain improvements in draft-equalizers; andit is peculiarly adapted to eveners for four or more horses, wherein itis desirable for any reason to attach the evener to the plow or othermachine or vehicle to be drawn at a point other than the normal centerof draft. Its construction and mode of operation are fully set forth inthe following specification and claims.

In the drawing, A represents the plowbeam, and B a four-horse evener,which is attached to the plow-beam by the clevis O in the ordinary way,but at the point a at one side of its center. To the longer arm b of theevener B is clevised the doubletree D in the ordinary way with itswhiffletrees W W. The evener bears near the end of its shorter arm I)the horizontally-mounted sheave S, and also the corresponding sheave s,also horizontally mounted a short distance from the point a on thelonger arm. The chain or cord 0' is attached to the plow-beam at anyconvenient point, as O, to the rear of the point a, carried around thesheave s in front and the sheave S behind, as shown in the drawing,terminating in the ring R, to which is clevised the doubletree d, whichis provided with whiffletrees W W.

In practice I make the sheave s with as small a diameter as possible, asI find that construction gives the best results.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In combination, in a draft-equalizer, an evener having itsattaching-point to one side of the center of draft, draft devices ateach end of said evener, a connection between one of the devices and theevener, and a connection between the other device and the object to bedrawn to the rear of its connection with said evener, substantially asdescribed.

2. In combination, the evener, adapted to have the load connectedthereto to one side of the center of the draft, draft devices lo= catedat each end of said evener, a connection between one of said devices andthe evener, and a cable or chain secured at one end to the load and atits opposite end the other draft device, said chain or cable having aninter mediate connection with said evener, substantially as described.

A draft-equalizer comprising the evener B, having its point ofattachment to the plow or other object to be drawn at one side of thecenter of draft, the horizontal sheaves 8 and S on the evener, the chainc passing over said sheaves and attached at one end to the plowbeam atthe rear of its point of attachmentto the evener, the doubletree 01attached to said chain at its opposite end at the shorter end of saidevener, the doubletree D and the whiffietrees as shown and set forth.
